Walk to any Costco in NYC and you’ll see plenty of people doing just fine with 50+lbs of groceries and a shopping cart.
Alternatively, go to any suburban grocery store and you’ll see people driving away in massive pickup trucks and SUVs having only picked up a gallon of milk.

It's not about need. Most of those people didn't choose the massive truck or SUV because that was the most sensible vehicle for them. They bought it because they like it.
Even if they don't strictly need to drive their truck to the store, they still will because they like driving it. It's not a wildly different mindset from people who buy the latest and greatest phone every year or spend thousands on a wristwatch that keeps time worse than a $20 digital watch you buy in a drug store.
I've lived in cities and depended on public transportation when I was younger and now I'm out in the 'burbs. Right now, the suburbs is where I want to be. My quality of life is higher. If I had a self-driving car, I'd move even further out of the city.
Do some people drive because they like it? Yes
Do some people drive because it’s required to do anything based off of a car-centric environment? Yes
If I do need to make a larger trip, I bring a folding wagon. It’s less convenient than just stopping by on my way home from something else but there are two full grocery stores within a 5 minute walk of home so it’s no big deal. Same as before, minimal lines.
I’m about to move to the suburbs where the nearest large grocery store will be a 7-minute bike away, so I’m planning to get a front-loader cargo bike like the Urban Arrow: https://na.urbanarrow.com/family-bikes/
…though while it is that short of a trip taking a direct route, that route seems somewhat inhospitable outside of a car, so in practice I might have to take some long detours. The town’s supposedly planning to put in bicycle infrastructure at some point, but I think that’ll be my rallying cry once I move there. :)
